Misted double glazing & condensation between panes fixed in Daventry
Looking for misted window repair in Daventry? Condensation trapped between the panes means the seal on your double glazed unit has failed. In Daventry we measure, make and fit a brand-new sealed unit into your existing uPVC, aluminium or timber frame — restoring clear views and insulation for a fraction of the cost of a new window.
- Local engineers in Daventry
- No call-out fee
- Guaranteed workmanship
Signs your sealed unit has blown
- Visible gaps or cracks in the spacer bar around the edge
- Room feels colder near the window than it used to
- Fog or droplets between the two panes that won't wipe off
- Mist that comes and goes with the weather and sunlight
- White streaks or cloudy staining inside the glass
How we replace a misted unit
1. Measure
We measure the glass precisely and check the frame, beads and drainage.
2. Manufacture
Your new unit is made to size — clear, obscure, toughened or A-rated energy glass.
3. Fit
The old unit comes out, the new one goes in and the beads are refitted. Usually under an hour per window.
Replacing only the glass unit keeps your frames, avoids building work and typically costs far less than a whole new window.
The real causes behind misted window repair jobs in Daventry
Poor original fitting
Units fitted without proper packers can sit on the frame unevenly, putting pressure on one corner and splitting the seal early.
Sun and temperature swings
South and west-facing glass heats and cools every day. That constant expansion and contraction stresses the edge seal until it fails.
Age of the seal
Sealed units are bonded with a perimeter sealant that slowly breaks down. After 10–20 years many units start letting moist air in between the panes.

Misted window repair in Daventry: FAQs
Can I upgrade the glass at the same time?
Absolutely — choose obscure privacy glass, toughened safety glass or higher energy-rated glass.
Why is there condensation inside my double glazing?
Condensation between the panes means the unit's seal has failed and moist air has got in. It can't be wiped away — the sealed unit needs replacing.
Can misted double glazing be fixed without replacing the window?
Yes. We swap just the sealed glass unit and reuse your existing frame, so there is no mess and no planning needed.
Is the new glass guaranteed?
Yes, every replacement sealed unit comes with our 10-year glass guarantee.
How quickly can you replace a misted unit in Daventry?
We measure on the first visit and return to fit once the unit is made — usually within one to two weeks.
